The Wacker Neuson Spring Pin is a genuine OEM component designed for the APT4S and APT4T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a direct OEM replacement, this spring pin is manufactured to the same specifications as the original part, ensuring a proper, accurate installation every time. Compatible across the full APT4S and APT4T lineup, part number is the correct choice for restoring your pump to proper working order.
Key Features
- Genuine OEM Construction — Manufactured to exact Wacker Neuson tolerances, ensuring the spring pin delivers the retention force and dimensional fit the original design requires.
- Drop-In Replacement — Engineered to seat and function identically to the original, allowing straightforward installation without reworking surrounding components.
- Broad APT Pump Compatibility — Fits APT4S and APT4T pump models in standard, surge brake, electric brake, and cold weather variants, covering both skid-mounted and towed configurations.
- Maintains Pump Integrity — A correctly fitted spring pin keeps fastened assemblies securely located; a worn or missing pin can allow critical components to shift under load, leading to accelerated wear or mechanical failure.
- Verified Part Number — Ordering by Wacker Neuson part number 5200020033 confirms you receive the exact part specified for your machine, eliminating guesswork on fitment.
A spring pin — sometimes called a roll pin or slotted spring pin — is a hollow, cylindrical fastener with a longitudinal slot that allows it to compress slightly as it is driven into a drilled hole. This compression creates a tight, secure fit that locks shafts, levers, and other components in position relative to one another. When a spring pin wears, shears, or works loose, the components it retains can shift or separate, causing misalignment, erratic operation, or further mechanical damage to surrounding parts.
